OpenTofu vs Terraform: A Practical Migration Guide for Enterprise Infrastructure Teams
HashiCorp's BSL license change created a fork in the infrastructure-as-code landscape. OpenTofu 1.x has reached production maturity for most enterprise use cases — here is what the migration involves and where you should still proceed carefully.
PostgreSQL Major Version Upgrades: A Risk-Managed Approach for Production Systems
Upgrading PostgreSQL major versions is more involved than a minor version patch but less disruptive than a full database migration. We walk through the pg_upgrade approach, the parallel server method, and how to validate data integrity and application compatibility before cutting over.
